Surely your joking, Mr. Hein! :-)

Achim,
I'm having almost the same problem - overlaying some data on the topography.
I figured that the best way is the following sequence :
shade_surf, topo, shades = data,.... // place your favortie angles of view etc
surface, topo, /noerase, .....
Additional parameters to both surface routines must be the same. First one
plots shaded surface with topography colored with your data and second
statement overplots topography grid, to make it visible.
Maybe this helps.
